ENGINE MOUNTING Oct. 27, 1931.

Original Filed se t. 16, 1927 1N VENTOR K Rei ssued Oct. 27, 1931 UNITED STATES PATENT OFFICE ROGER K. LEE, OF HIGHLAND PARK, MICHIGAN, ASSIGNOR "IO CHRYSLER CORPORA- TION, OF HIGHLAND PARK, MICHIGAN, A CORPORATION OF DELAWARE OUNTING Original No. 1,788,878, dated January 13, 1931, Serial No. 220,027, filed September 16, 1927. Application for reissue filed March 12.,

This invention relates to engine mountings and more particularly to the mounting of an internal combustion engine an an automobile frame.

It is well known that rotation of the crankshaft of an internal combustion engine causes a periodic vibration due to the torque or twisting action of the shaft. This vibration or vertical movement is usually transmitted to the frame and thus causes obj ectionable noise in the parts associated with the engine. It is therefore a primary object of my invention to provide .an engine mounting whereby the torque action may be absorbed by a frame connection independent of the weight supporting member. I

A further object of my invention is to provide an engine mounting in which the weight of the engine may be supported by a resilient member provided for the absorption of the torque action.

With the above andother objects in view, my invention consists in the arrangement, combination and construction of the Various parts of my improved device as described in the specification, claimed in my claims and shown in the accompanying drawings, in which:

Fig. 1 is a side elevation of an internal combustion engine mounted in an automo-w bile frame in accordance with my invention.

Fig. 2 is a sectional view taken on line 2'2 of Fig. 1.

I have shown an internal combustion engine indicated generally at 5 having a flywheel housing 6 at the rear end thereof. Bolted at 80 to the engine casing is acrankcase 1(0 within which is positioned the crankshaft Conventional side channel members of an 7 automobile frame are shown as at 9, between which are positioned, at'front and rear, channelshaped supporting cross members 8.

The crankcase 10 is supported at the centers of the frontcross members 8 by means of two rubber blocks 11 positioned on, either side of one flange of the cross member, between the bottom of thecrankcase and the supporting plate 20, respectively. The blocks are loosely secured in place by means of 1931. Serial No. 522,113.

bolts 12 and nuts 13, so as to permit slight movement thereof when the structure is in motion. It will be noted that the entire weight of the motor is carried at this point, in

the front and rear, and that the resilient support will tend to absorb any slight vibration which may be present.

The housing 6 is provided with flanges 33 at each side thereof and resilient means,

ized for the purpose of absorbing the vertical movement or torque reaction caused by rotation of the crankshaft 7'. This results in an engine mounting which is exceptionally quiet, as well as one in which the vibration is successfully eliminated independently of the load carrying member.

It will be obvious that various changes may be made in the arrangement, combination and construction of the various parts of I my improved device without departing from the spirit of my invention and it is my intention to cover by my claims such changes as may be reasonably included within the scope thereof.
